Members of a new caravan of at least 500 migrants told Fox News late Monday that they have begun its journey from a bus station in Honduras to the United States border.

The caravan left the northern city of San Pedro Sula earlier than expected. There was talk on social media that the group was going to leave at 5 a.m. on Tuesday. It is unclear why the group left earlier, but rainy weather could have played a role.

The group consists of a mix of people that included some mothers carrying their young children on their shoulders. Reports say the group will rest in the Honduran city of Quimistan, which is 35 miles from the bus stop, as an early checkpoint.

As they walked, migrants begged local store owners to give them food or water for their journey, according to the Associated Press.
